Qualifications

• Bachelors/Masters in Electrical/Electronics, Embedded Systems, Mechatronics, or related.
• 3-8+ years experience in system testing/validation of embedded ECUs (automotive/industrial).
• Strong understanding of Motor control systems and inverter basics (PMSM/BLDC/IM fundamentals helpful) ECU testing lifecycle, test design techniques, and defect management.
• Hands-on experience with at least one: HIL platforms (dSPACE, NI, Vector, etc.)
• Bench testing with inverter + motor setups and measurement equipment.
• Comfortable with automotive networks & tools: CAN/LIN/Ethernet, UDS diagnostics, CANoe/CANalyzer (or equivalent).
• Strong analytical and problem-solving skills.
• Excellent communication and cross-functional collaboration.
• Ability to manage multiple integration tasks across vehicle programs.
• Detail-oriented with a focus on safety, performance, and reliability.
• Passion for electrification and automotive innovation.

Responsibilities

• Create and maintain system test strategy, test plans, and test matrices aligned to product requirements.
• Derive test scenarios from system requirements, use cases, and safety/quality goals.
• Define test coverage across operating modes (normal, derating, limp-home, fault modes) and environmental conditions.
• Develop and execute tests for motor control MCU functions, such as: Start/stop sequences, torque/speed control response, mode transitions Regeneration and braking coordination (where applicable) Thermal derating, voltage/current limitations, and protection behaviors.
• Build and automate tests on HIL rigs (e.g., dSPACE/NI/Vector), and bench setups including inverter + motor + load.
• Develop automated regression suites for repeated validation: Test scripting (Python/CAPL/MATLAB/Simulink Test or tool-specific frameworks) CI-friendly execution and reporting (where applicable).
• Maintain test artifacts: scripts, configuration files, datasets, and baselines.
